was like 400 or 500 for mine and i gained about 10-15 kW when i went 3" mandrel from 2.5"

standard is only 2.25 " or 2" from memory

very much worth it.

You will most definately notice the difference however the biggest increase is noticed when a 3" dump pipe is used as well.

I got a custom 3in exhaust including a cast 3in dump pipe and 3in muffler (had to for the defect notice) and it cost me $700. Tune the fuel pump to match and you'll be surprised at the gains in power. Turbo comes on earlier and for longer, which means smoother. Well worth it. As hoonz said just do it already. :D

dyno sheets dont mean crap.. I can put a car on a dyno, get one hp figure, play with a few "air settings" on the system, and it will give a hole different hp figure to the one before.. :?

yea trillion variables with dynos, but trying to gather fact from fiction. Some say they gain X kw, but its guess work..

like people with extractors that gain 12309203984203948023948kw at the gearstick
